Question for unbiased gamers regarding portable gaming

I want a portable device for gaming. I'll be taking a long trip in a few weeks so I want to get something to entertain myself.

I have considered what I feel to be the two best options.

1) A Nintendo 3DS XL with preloaded Mario Kart 7

price $199.99

pros: 3DS has several great AAA titles to buy and many more coming out next year: I.e. - zelda, mario 3d world, star fox, pokemon, fire emblem, monster hunter etc.

cons: games are pricey averaging $39.99

2) A Google Nexus 7 16 gb

price $199.99

pros: games are extroidinarily cheap, betweeen 10-20% the cost of a 3DS title.

cons: games most likely aren't going to be as involved or fun as a 3DS game. While it's true they are graphically superior by a mile (due to UE3 and other engines), that doesn't necessarily make them fun. I have the impression that even some of the coolest looking games like NOVA 3 and Wild Blood will probably lose my interest after 10-15 minutes of playing. I can't see most if not all tablet games have the depth and variety in gameplay that a 3DS title would.

Also worth mentioning is that the control scheme on tablets is definitely inferior... the buttons on a 3DS should provide a more easily controllable experience.

What do you guys think? They are basically the same price, one comes with a AAA title, the other doesnt. However purchasing future 3DS titles will cost considerably more, but most likely capture my attention span for longer periods of time.

The only thing we really play on Sony PlayStation 3 is Catherine. The rest we beat fast like the fist day we bought them. The other types of games like Kill Zone Call of Duty are just played until they are wore on the enthusiasm.

The most gaming we do is computer gaming like Some WOW but that has gotten boring and pretty much shelved and left to idle there. We play Aion and it fun to make your character and such but can become boring also. Tera was great fun especially the white lion mount on the special edition played it with lots of fun then tired of it also.

I sit and play Jewel Quest II every day I keep that game up on a computer ready for the next tournament game and player.I like it the best for every day playing. WOW and Ion is still going also but I really like the Jewel Quest II.

Portable systems hand held

3DS is the only choice for best hands down game titles that are fun.

Yet the PlayStation Vita offers so many more features than the other hand held models it has many many other games the other ones do not offer......but expensive.

I like competition and a challenge love a challenge and love art and such like the graphics and making my own equipment and gear like dying it customizing it....
